To all whom it may concern:

Be it known that l, CHRIST MARCHINS, a citizen of the United States, residing at Portland, in the county of Multnomah' and State of Oregon, have invented new and useful Improvements in Hair-Cutting Devices, of which the following is a specification.

This invention relates to improvements in hair cutting devices, and particularly to a hair cutting device designed to facilitate the cutting of the hair of one person by another, as well as to enable a person to cut his own hair. n

One object of the invention is to provide a device of the character described embodying suitable supporting means carrying a stationary or gage comb, and clippers mounted upon the supporting means for travel relative to the stationary comb, by means of which the hair may becut in a ready and expeditious manner.

A further object of the invention is to provide a device of the character described which may be supported from the neck of the wearer while the hair at the back of the head is being operated upon so as to obviate the annoyance and tedious strains upon the hand of the operator in working the clippers, particularly when the clippers are employed solely as the cutting implement.

A still further object of the invention is to provide an operating handle which may be readily engaged and operated while the cutting mechanism is supported, so that any person may cut the hair upon the top and back of his head to any desired degree and with ease and facility.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings in which Figure 1 is a view of the device illustrating its mode of assemblage and use by a person in cutting the hair upon the back of his head. F ig. 2 is a top plan View of the same. Fig. 3 is a vertical transverse section of the frame and cutting mechanism of the device with the neck support and auxiliary handle removed. Fig. 4 is a front elevation of the same. Fig. 5 is a vertical longitudinal section taken on a line through the ratchet mechanism and clipper feed gearing. Fig. 6 is a vertical transverse sectlonthrough the same. Fig. 7 is a top plan View of the which the stem 5 extends.

auxiliary handle, a part appearing in secrods 4 and a lower threaded rod or stem 5, 1

which members are united at their outer ends by a V-shaped bracket 6. The threaded stem 5 is fitted at its ends in openings in an arm 7 forming part of the plate 1 and the vertex portion of the bracket 6 in such a manner as to be removable from the frame, so that threaded stems having threads of different pitch or degrees of fineness may be employed whenever desired. As shown in the present instance the front end of the stem 5 is formed with a reduced portion or lug 8 detachably fitting within an aperture 9 in the arm 7 of the plate 2 and at its rear end is provided with a reduced threaded portion 10 engaging an opening 11 in the bracket 6 and secured in position by a nut 12. The front ends of the bars 1 may be fixed to the plate 2, and said bars have angular projections 13 at their rear ends projecting through slots 14 in the bracket 6 and fitted with cotter pins or keys 15, upon removal of which pins or keys and the detachment of the nut 12 the stem 5 may be removed and a different stem substituted therefor.'

The bars or rods 4 form guides, 'in conjunction with the stem 5, for a movable cutter. This cutter comprises a pair of clippers of generally conventional construction and including a comb plate 16, cutter plate 17, fixed and movable handles 18 and 19 and the usual spring (not shown), whereby the cutter plate is retracted or moved in one direction. As shown the sides of the comb plate 16 have guide notches 21 to receive and engage the bars 4, and the casing and fixed handle member 18 of the clippers are fixed to a movable carriage formed of a bar 22 and a U-shaped guide bracket 23 fixed to said bar, which bar and yoke are provided with circular bearing openings 24: and 25.

Inclosed between the bar 22 and bracket 23 of the carriage is a traveler formed of front and rear sup )orting members 26 and 27 having tubular ournals 28 and 29 fitted to turn within the bearings 24 and 25 and through The front supporting member 27 has a portion of angular form to form a key which fits within a slot in a ratchet wheel 30, held from displace ment by retaining pins 31, while the upper supporting member 26 forms a support for a split nut 32 which engages the threads of the stem 5.

The nut 32 is composed of two sections 33 and 34 which fit within receiving slots or recesses 35 formed in the member 26 and are connected at one end by a connecting plate 36 secured thereto by suitable fastenings 37, the opposite ends of the nut sections being engaged by an adjusting screw 38, whereby the nut sections may be adjusted to engage the threads of the shaft or moved out of engagement therewith, so that the carriage will be connected for travel upon the stem or freed therefrom so that the carriage and cutter may be moved with freedom forwardly or rearwardly upon the shaft to enable a quick adjustment to be secured. It will also be understood that this construction allows nuts having threads of different size or pitch to be used for cooperation with fine or coarse threaded uprights 5. Fixed to the movable handle 19 of the movable cutter plate of the clippers is an arm 39 to which it centrally connects a U- shaped double dog or pawl 40, the ends or arms of which are respectively provided with channeled ends 41 and 42, for guiding engagement with the toothed edge of the ratchet wheel 30. One of these end portions, the end portion 41, is plain surfaced to ride back and forth over the teeth ofthe wheel, while the other end portion 42 is provided with an inwardly projecting tooth 42. When the handle 19 of the clippers is moved toward the handle 18, the arms of the dog are spread and the dog bowed outward or expanded, and the channeled end 41 of one dog interlooks with a tooth of the wheel and prevents retrograde motion of the wheel, while the channeled end 42- of the other dog rides backward over the teeth of the ratchet wheel. WVhen the movable handle 19 is then relaxed, and is moved backward by the retracting spring of the movable cutter plate, the dog is contracted by its own resiliency, the arm 41 in this action riding backward over the teeth of the gear while the tooth 42 of the arm 42 in this action engages a tooth of the ratchet wheel and feeds said wheel forward. Thus it will be understood that intermittent motion will be communicated to the nut upon the carriage for the transaway from said plate, so as to gradually and uniformly cut at different distances therefrom, by which means it will be evident that the operator may cut or shingle the hair at the back or sides and work upwardly in the usual way so that the hair will be cut close to the head, at the lower marginal edge of the hair and then at different distances from the head to conform to the contour thereof. By this construction and mode of use the cutter may be operated to greater advantage and with less skill, to produce good results, than is necessary in the use of an ordinary pair of clippers or scissors in free hand cutting.

In order to enable the device to be supported in position while being used, so that any person may conveniently cut the hair upon the back of the head, I provide supporting and auxiliary operating means, which I will now proceed to describe. The supporting means consists of a yoke 43 which is adapted to be applied about the neck of the wearer, so that the device may be supported in position. To one of the ends of this yoke is attached one end of a fastening strap 44, the free end of which is adapted to engage a buckle 45 upon the opposite end of the yoke, by means of which the open space or throat of the yoke may be closed to return the device in position against rearward displacement. The yoke is attached and carried by a collar or sleeve 46 slidably mounted upon an auxiliary operating handle 48, said sleeve being provided with laterally projecting apertured ears 49 between which the sides of the offset 46 fit, and which receive pins or keys 50 to detachably secure the parts together. sleeve or collar 46 is attached to one of the stretches-of a flexible wire or cable 51 passing through slots 52 in the handle and over guide pulleys 53 arranged therein, thus adapting the collar to be freely moved in either direction on the handle to any de sired working position by means of which the cutter may be adjustably supported, as hereinafter fully described. The handle 48 may be in the form of a bar of any suitable length to reach from a suitable point at the front to the back of the head, so that it may be manipulated by the operator in using the device to cut the back of his own hair. This handle bar is adapted for attachment at its rear end to the fixed and stationary handles 18 and 19 of the clippers, and to this end the bar is provided with a slot 54 to receive the end of the handle 18 and carries a spring actuated locking dog 55 to engage a keeper opening 56 formed in said handle 18, by which the same will be detachably secured to the handle bar. The movable handle 19 of the clippers is formed with notches 57 to receive a slotted connection 58 upon one end of an actuating The cord or wire 59 passing over a guide pulley 60 arranged in a slot 61 in the handle bar intersecting the slot 5 and which cord 59 passes through a guide groove 62 in one side of the handle bar to a point near the front end of said handle bar, where it passes outward laterally through a guide slot 63 and over a pulley 64 arranged therein, and is attached to the angular arm 65 of a bell crank shaped movable operating handle 66 pivoted to the front end of the handle bar and arranged opposite a fixed handle or grip 67, by means of which the handle bar may be held and the actuating cord manipulated to operate the movable handle of the clippers in a manner readily understood. By this construction it is evident that the clippers may be operated from a distant point so that the hair at the back of the head maybe cut from the front by arranging the device as shown in Fig. 1, so that anyone so desiring may cut his own hair with ease and facility.

I claim v 1. A hair cutting device including a handle, a neck yoke, and means upon the hafldle bar for connecting it with the neck yo e.

2. A hair cutting device including a supporting frame, a cutter mounted to travel upon the frame, and including fixed and movable handles, a handle bar adapted to detachably engage the fixed handle, means upon the handle bar for transmitting mo tion to the movable handle, a slidin collar on the handle bar, means for adjusting the same, a neck yoke carried by said bar, and a closure for the throat of said yoke.

In testimony whereof I afiix my signature in presence of two witnesses.
